A unique cage-like structured carbon-composed Raney Nickel catalyst reinforced with in-situ grown carbon nanotubes is reported in this paper. Phenol formaldehyde resin was selected as carbon precursor to prepare this catalyst. NiAl alloy powder (48 wt% Ni) and powdery phenol formaldehyde resin were mixed firstly, and then the mixture was compressed, cured and carbonized, followed by alkaline leaching. The prepared carbon-composed catalyst possesses high stiffness, good hydrogen adsorption capacity, and perfect catalytic property. Hydrogenation of n-butyraldehyde to n-butanol was selected as a probe reaction. Compared with commercial catalyst, this cage-like carbon-composed Raney Nickel catalyst exhibits much higher selectivity and similar catalytic activity. It is believed that the use of carbon composing method will make a series of Raney metal catalysts, including but not limited to Raney nickel, Raney cobalt, and Raney copper, very important fix-bed catalysts for chemical industry.

新型阮内镍固定床反应催化剂的制备与应用

本文报道了一种独特的笼状结构碳复合阮内镍催化剂,该催化剂用原位生长的碳纳米管增强。选择苯酚甲醛树脂作为碳前体以制备该催化剂。你首先将铝合金粉末(48 wt%Ni)和粉状酚醛树脂混合,然后将混合物压缩,固化和碳化,然后进行碱浸。所制得的含碳催化剂具有高的刚性,良好的氢吸附能力和良好的催化性能。选择正丁醛加氢成正丁醇作为探针反应。与市售催化剂相比,这种笼状碳组成的阮内镍催化剂具有更高的选择性和相似的催化活性。相信使用碳组成方法将制造一系列阮内金属催化剂,包括但不限于阮内镍,阮内钴和阮内铜,它们是化学工业中非常重要的固定床催化剂。
